answer
x=14
Step-by-step explanation:
4.5(8-x)+36=102-2.5(3x+24)
36-4.5x+36=102-7.5x-60
-4.5x=42-7.5x
7.5x-4.5x=42
3x=42
x=42/3
x=14
Answer:
Hello from MrBillDoesMath!
Answer:
P = 67, Q = 37
Discussion:
Let Q = 37 ( the constant term on the right side of the = ) and
let P = 67 ( the coefficient of x on the left side of the = )
Then the equation becomes 67x + 37 = 67x + 37
which is true for infinitely many x

Answer:
33
Step-by-step explanation:
split it in to two shape 3*7 and 6*2
7*3=21
6*2=12
21+12=33
100 kilometers you solve with a proportion 2/20=10/x
2x=200 so x=100
Answer:
Area of Pool cover: 110.25π
Length of rope: 21π
Step-by-step explanation:
To find the area of a circle the formula is πr^2.
1. take 10.5, which is half of the diameter and multiply it by itself then multiply by pi(π). Answer is 110.25π
To find the length of the rope(circumference) the formula is 2πr.
1. Take r, which we established as 10.5 then multiply it by 2, which is 21. Then multiply by π. Answer is 21π

If ur teacher wants you to use 3.14 as pi then these are your answers:
Area of Pool cover: 346.185, round up to 346.19 if needed
Length of rope: 65.94
